What’s happening:

• Following its $20 million Series A round in August 2023, Socket has now raised an additional $40 million in Series B funding led by Andreessen Horowitz. The fresh capital will fuel the expansion of Socket’s open-source cybersecurity platform, which detects threats in software dependencies. 

Why it matters:

• Open-source software is an important part of modern technology infrastructure but the rapid adoption of open-source components makes it vulnerable to dependency attacks. With the new funds, Socket has the resources to scale its security solutions. 
• Socket’s solutions help developers catch threats early, preventing costly breaches and securing a critical aspect of software development.

Socket’s strengths:

• Uses AI to analyze software dependencies, allowing the platform to effectively identify vulnerabilities and prevent zero-day supply chain attacks.
• Socket's platform is designed to continuously monitor open-source packages for threats, allowing it to detect and block malicious behaviors such as malware, backdoors, and typo-squatting in real time.
• The platform is tailored for developers, allowing them to integrate security measures into their workflows without affecting speed or efficiency. 

By numbers:

• Founded in 2020, the company expanded from 5 employees to 32 and aims to reach 100 within a year.
• The startup secured $20 million in a Series A round in August 2023 and a $40 million Series B in 2024.
• It is anticipated to grow revenue by  400% in 2024. 

What next:

• Socket plans to use its funding to hire more engineers, product people, designers, and salespeople and try to deliver its roadmap faster for its customers. It looks to expand its workforce from 32 to 100 employees.
• It will use investor networks, like Andreessen Horowitz and Abstract Ventures, to grow more efficiently and extend market reach. 
• The company aims to develop more features tailored to enterprise needs while continuing to refine its platform's capabilities in response to evolving software threats.

Key players:

• Stripe: A global leader in payment solutions, previously pulled out of crypto but returned with new crypto-payout options and fiat-to-crypto on-ramps. 
• Bridge: Founded by Zach Abrams and Sean Yu, both with previous experience at Square and Coinbase. Bridge simplifies global payments using stablecoins through a seamless API.

What’s happening:

• Stripe has acquired Bridge, a crypto payment startup that simplifies the use of stablecoins for payments through a single API. This acquisition reinforces Stripe’s commitment to cryptocurrency payments, following its re-entry into the space after ending Bitcoin support in 2018. 
• By integrating Bridge's platform, Stripe aims to expand its crypto-payout capabilities, especially in regions with inefficient banking systems

By numbers:

• The acquisition comes at a time when the stablecoin market has seen significant growth, with market capitalization rising from $62.7 billion in 2021 to $172.6 in October 2024.
• The stablecoin market peaked at $181.7 billion in February 2022.
• Bridge raised $58 million in venture capital before its acquisition by Stripe.
• Bridge’s acquisition of $1.1 billion is Stripe’s largest acquisition to date and one of the biggest in the crypto industry.

Going deeper:

• Stripe’s acquisition of Bridge underscores its belief that blockchain-first ecosystems will eventually dominate fintech. By utilizing Bridge's APIs and stablecoins, Stripe is leading the next wave of fintech innovation. 
• The acquisition also signals a larger shift in the industry, as more companies are expected to move away from legacy payment systems toward blockchain-based solutions. This defines the future of international financial transactions.
• Stablecoins provide a more efficient, secure, and cost-effective alternative to traditional fiat payments.

What's happening:

• Paebbl is working towards carbon mineralization by capturing CO2 from industrial emissions and turning it into valuable building materials. 
• The startup has raised $25 million in a funding round led by Berlin-based venture capital firm, Capnamic. Participants included Amazon and German cement industry leaders Holcim and Goldbeck.

The big idea:

• Paebbl's core technology focuses on carbon capture, utilization, and storage (CCUS), which fastens the natural process of carbon mineralization. By converting captured CO2 into solid carbonate materials, the startup aims to create a circular economy where carbon emissions are repurposed instead of being released into the atmosphere.

• Paebbl’s approach addresses the urgent need for carbon reduction and offers a sustainable solution to the construction industry.

Why it matters:

• Paebbl's funding highlights the increasing role carbon removal technologies will play in addressing the climate crisis. With rising global temperatures, there's a need for solutions that can capture and store carbon dioxide effectively.
• Paebbl's technology could offer a scalable, cost-effective solution to reduce greenhouse gas emissions and promote a sustainable future.

By numbers:

• Paebbl raised $25 million in its latest funding round.
• The startup’s new facilities will increase its production capacity tenfold to 3 tons of rock powder per day.
• Paebbl aims to bring 1 million tons of its carbon-based building materials to the market by 2030.

What next:

• Paebbl is now focused on scaling up its operations, with plans to open its first commercial-scale plant by 2027. 
• The company will strategically place these facilities in regions with high demand for building materials, access to CO2 feedstock, and renewable energy sources.
